摘要：

The preparation and the morphology, structure, functional groups, and electrocatalytic oxidation ability of novel carbon nano-fragments (CNFs) derived from the graphite anodes in spent lithium-ion batteries have been investigated. Utilizing the interlayer space increase, layer distortion and remnant lithium of the lithium-intercalated graphite, the oxidized CNFs are prepared through a chemical oxidizing-ultrasonic crushing process. The spectroscopic results demonstrate that the as-prepared material has nano-fragment appearance, abundant oxygen-containing functional groups and disordered carbon. In addition, it exhibits excellent electrocatalytic oxidation and resolved ability to hydroquinone and catechol isomers, showing potential application in the electrochemical fileds.
